Title: High speed searching method for rotary head type digital audio tape recorder
Inventor: ISHIMOTO MASANOBU
IPC: G11B27/28
Filed: 1988-07-05
Abstract: PURPOSE:To improve the reliability of high speed search operation by reproducing program time information (P-time) for the recording period of start identification information (start ID). CONSTITUTION:When the high speed search of the start ID, which is recorded to a sub code area on a magnetic tape 22, is executed and a recorded main signal is reproduced near the starting edge of the start ID, the P-time in the termination of the start ID is reproduced. Only when the P-time at such a time is coincident with the recording period of the regular start ID to be already determined, the tape 22 is rewound up to the starting edge of the recording period for the start ID and after that, the main signal is reproduced. Accordingly, when the high speed search to use the start ID is executed in the tape 22, to which the start ID of the short recording period, is recorded, the lacked start ID is prevented from being judged as the regular start ID. Thus, the reliability of the high speed search is improved.

Abstract: PURPOSE: To obtain satisfactory fuel increase adjustment characteristic at time of heating a device by providing a water temperature signal control circuit to increase a water temperature signal to be input to a quantity increasing circuit by a prearranged value so that when the value of a water temperature signal to be indicated by a water temperature sensor has exceeded a prearranged value, the water may be adjusted to be increased.  
     CONSTITUTION: An ignition signal to be given by an ignition coil 18 is shaped in terms of wave form by means of a wave-form shaping circuit 20 and is frequency- divided into halves, being input to an arithmetic circuit 22. The arithmetic circuit 22, while an input signal is at high level, charges a built-in charging/discharging condenser at a constant charging current. The condenser discharges an electric current when the input signal has changed to a low level. At that time, a discharged current is discharge-controlled in accordance with an output voltage on an air flow meter 12. The output of the arithmetic circuit 22 is input to a quantity increasing circuit 24 and the quantity increasing circuit 24 is adjusted to increase the quantity when the output of a thermister 16 to detect an engine cooling water has increased beyond a prearranged value. After this process, the output of the said circuit controls a fuel injection valve 14 through a drive circuit 26.

Title: Estimation system for operation time of robot
Inventor: SUGINO KAZUHIRO
IPC: G05B19/18
Filed: 1983-09-14
Abstract: PURPOSE:To estimate the operation time of a robot even when operation characteristics are unknown by representing the operation characteristics of the robot by the movement distance of each shaft and its required time, and estimating the operation time from data for the operation. CONSTITUTION:Control data for operation is transferred from a disk 2 to a storage device 11 firstly. A control data analyzing device 7 decomposes said control data stored on the device 11 into a set of operation data X for operating respective shafts of the robot 1. An operation time calculating device 8 extracts one of the operation data for work and calculates the operation time of each shaft by using the relational expression between the angle of rotation of each shaft and its necessary time. Then, a maximum decision device 9 selects the maximum value among the calculated operation times of the respective shafts. This value is added by an integrating device 10 until all operation data are handled, and the operation time of the robot 1 for the control data for the operation is obtained by the device 10.

Title: High frequency heating device with heater
Inventor: UENO AKIHIKO
IPC: H05B11/00
Filed: 1988-07-06
Abstract: PURPOSE:To prevent local heating and enhance the safety by furnishing a control circuit equipped with timer function, subjecting a plurality of heaters to time divided control, and stopping current feeding when the max. service time for heaters is exceeded. CONSTITUTION:A high frequency oscillator 3 feeds high frequency current to a heating chamber accommodating the food, and heating is made with heating means 1, 2. The internal temp. of the chamber is sensed by a temp. sensing means 13, which stops heating when high temp. is generated due to failure in a thermistor 12 or a time division circuit of a control circuit 7. This circuit 7 performs heating control of the heating means 1, 2 with the aid of a microcomputer in accordance with the sensed temp. At this time, the means 1, 2 are not simultaneously heated under control of time division and a timer circuit incorporated in the circuit 7. The heating is stopped when the specified heating time by either means 1 or 2 is exceeded. Thus local heating is well prevented to ensure safety.

IPC: H04L12/46
Filed: 1992-06-26
Abstract: PURPOSE: To sharply reduce a buffer memory size while keeping the packet loss in an allowable level. CONSTITUTION: A target circuit network having dynamic lists 22A and 22B for tracing a data packet to be transmitted and received with at least one of two circuit networks uses a semi-double medium and a CSMA/CD protocol. A circuit network protocol parameter is adjusted for guaranteeing or rejecting a priority order to the circuit network in the case of collision based on the continuous observation of those two lists. Then, a back-off value for deciding the length of a time in which a bridge device 10 waits until the data packet is re-transmitted in the case of collision is corrected. A back voltage in the form of a carrier signal is applied to the circuit network for rejecting the use of this target device by another device when a buffer storage device 20 in the bridge is already full, and the data packet to be transmitted to the circuit network is absent.
